Elephant Robotics Catbot vs KUKA LBR iisy 3 R760: Robot Comparison
Updated: 4 hours ago
IN A NUTSHELL
🔎 THE KEY DIFFERENCE Both are compared at 3 kg. KUKA LBR iisy 3 R760 has the longer stated reach, which may help reach separated fixtures; it does not guarantee access at every tool angle. |
→ CONSIDER Elephant Robotics Catbot Consider it when its stated load and reach already cover your task and its controls fit your equipment. This article compares 3 kg and a 600 mm stated reach; include the gripper and part in the load. |
→ CONSIDER KUKA LBR iisy 3 R760 Consider it when reaching farther matters more than the higher payload of the alternative. This article compares 3 kg and a 760 mm stated reach; include the gripper and part in the load. |
💡 THE TAKEAWAY Check the real tool, movement path and safety assessment before choosing. A collaborative label does not make every task safe without guarding; compare complete installation quotes. |
Elephant Robotics Catbot vs KUKA LBR iisy 3 R760 is a choice about research, education and production fit. Elephant Robotics Catbot and KUKA LBR iisy 3 R760 differ in their working envelope, loading assumptions and engineering ecosystem. A useful decision starts with the exact mechanism and process, then checks whether either robot can execute the required path with the real tool attached. This comparison separates documented specifications from application-level engineering judgments.

Read the reach row together with the geometric notes below. Manufacturers may specify an arm-link sum, a wrist-centre motion area or reach to the flange; those dimensions are not interchangeable. The table does not establish access to every point at every tool angle. Controller references identify reviewed packages, and actual compatibility must be confirmed by model, software version and region.
Elephant Robotics Catbot: design and configuration
The Catbot, sold as the Elephant Robotics C3 in the C Series, is a six-axis collaborative robot with a payload of 3 kg, a working radius of 600 mm and a repeatability of ±0.05 mm. It is an all-in-one arm with the control electronics integrated in the robot body, intended for light commercial and industrial tasks such as assembly, pick and place and machine tending. The complete robot weighs 18 kg. The controller, end effectors, safety equipment and integration affect the final price and are quoted separately. Prices are indicative, are not final and may change. The Elephant Robotics Catbot fits manufacturers that want a robot working near people without full fencing, subject to a risk assessment.
KUKA LBR iisy 3 R760: design and configuration
The KUKA LBR iisy 3 R760 is assessed here at the reviewed 3 kg payload and 760 mm working reference, with 6 arm axes, ±0.1 mm repeatability and the KR C5 micro-2 controller scope. This is the six-axis iisy configuration, separate from the seven-axis iiwa. Validate the delivered iiQKA/controller generation, teaching workflow, contact conditions and full tool-load scope. A collaborative platform still requires an application risk assessment and does not approve hazardous tooling or unrestricted contact.
For this pair, KUKA LBR iisy 3 R760 offers 3 kg over the stated 760 mm reference, compared with 3 kg and 600 mm for Elephant Robotics Catbot example. KUKA LBR iisy 3 R760 has the larger stated distance by 160 mm, but this difference is only a preliminary layout indicator because reference points and joint envelopes can differ. Locate the actual fixture in each manufacturer model before treating this as usable extra working space.
Payload, tooling and a worked load example
Consider an illustrative total wrist load of 2.4 kg: a 0.6 kg tool and adapter package carrying a 1.8 kg part or product group. This arithmetic leaves 0.6 kg below the Elephant Robotics Catbot example’s nominal limit and 0.6 kg below KUKA LBR iisy 3 R760’s nominal limit. These are mass differences, not safety factors or a validated load approval. A heavy camera, valve block or retained material must be included before recalculating the total.
The example exposes the practical question: is the application limited by mass, by tool offset or by wrist rotation? Elephant Robotics Catbot is the lower-or-equal nominal payload choice in this pair. KUKA LBR iisy 3 R760 offers more or equal headline mass capacity, but that alone cannot approve an eccentric fixture. Moving the same mass farther from the flange increases the moment, and spreading it increases rotational inertia. Manufacturer load diagrams and the actual centre of gravity govern the final allowable motion.
Model the empty, partly loaded and fully loaded tool states separately. A vacuum layer gripper, a weld torch with hoses or an inspection head may change its effective loading during the cycle. Set the controller’s load data for each supported state and validate the transition logic. A payload table cannot predict acceleration derating, cable pull or transient reactions at a machine interface.
Reach, orientation and fixture access
Build the same cell model for both candidates: base height, machine opening, fixture datum, maximum part size, tool extension and access for maintenance. Elephant Robotics Catbot provides a stated 600 mm reference, while KUKA LBR iisy 3 R760 provides 760 mm. Check the deepest production pose and the return path with the loaded tool. An arm that just touches the target at full extension may have little freedom left to turn, retract or avoid a door.
For an education installation, fixture access includes supervised teaching positions and the instructor’s view of the mechanism. Choose exercises that fit the training arm’s intended scope. A production alternative may demonstrate a broader load or reach, but needs its own teaching enclosure, curriculum, service arrangements and supervised operating procedure.
Precision and throughput: compare the same task
The comparison uses ±0.05 mm for Elephant Robotics Catbot and ±0.1 mm for KUKA LBR iisy 3 R760. These figures should be read in their documented configuration scope. Repeatability is not absolute accuracy, camera calibration accuracy or finished-part capability. Fixture variation, TCP calibration, thermal conditions and tool compliance can dominate the error at the process point, especially when the tool extends far from the flange.
Ask each integrator to execute the same representative path with the same payload model, tool length, process dwell and stop conditions. Report transfer time, settling time, process time and waiting time separately. Published standard cycles often use different loads and distances; dividing one catalogue cycle by another would not establish the production advantage of Elephant Robotics Catbot over KUKA LBR iisy 3 R760. Use a measured or validated application cycle before assigning a throughput benefit.
Programming, controls and production integration
Elephant Robotics Catbot is paired here with the supplied model-specific control package, while KUKA LBR iisy 3 R760 uses KR C5 micro-2. Controller names identify the review baseline rather than a guarantee that all interface options are included. Compare the actual software revision, teaching workflow, diagnostic tools, fieldbus licences and recovery procedures. An existing trained team and reusable production code may outweigh a small dimensional advantage. Obtain a demonstration of the same machine handshake and interrupted-cycle recovery on both platforms.
Specify the PLC handshakes before ordering: cycle request, ready, busy, complete, fault, part present and recovery authorization. Define how an interrupted operation resumes without repeating a dangerous or quality-critical action. Vision, force sensing, fieldbus communication and external-axis coordination must be checked as explicit included or optional functions. An Ethernet connector does not by itself prove that a particular industrial protocol or software interface is licensed and supported.

Protection, installation and maintenance
Match the precise protection package to the process. Standard, protected, cleanroom, foundry and washing configurations can have different seals, services and maintenance requirements. Do not transfer the best optional IP or cleanroom rating to an unprotected base model. Check the controller location, cable bend radius, available lifting access and base reactions with the installer.
Treat safe operation as a property of the complete task and installation. Include the tool, sharp workpiece edges, trapping points, dropped loads and machine access. These robot systems require task-specific safeguarding; payload or compact size does not establish safe unguarded operation. Plan tool replacement and fault recovery without dismantling the whole installation, and include connector access, lubrication and spare-cable replacement in the maintenance layout.
Price and lifecycle value
Published arm list prices: Elephant Robotics Catbot is listed from $5,900 and KUKA LBR iisy 3 R760 is listed from $27,400. Request configuration-specific quotations for Elephant Robotics Catbot and KUKA LBR iisy 3 R760. An arm-only number is not the price of a commissioned production cell. Ask for separate line items for controller, pendant, communication options, end effector, safety equipment, installation, acceptance, training and warranty. Price changes, regional support and included software can reverse an apparent hardware-cost advantage. Compare the same delivered scope before calculating payback.
Compare the installed production scope: tool, fixtures, sensing, guarding, machine interface, programming, acceptance and training. For small-parts automation, include feeders, vision calibration, nests and rejected-part handling. Keep purchase cost and recurring support costs separate. No payback figure is defensible until the actual cycle, yield, utilization and installation quotation are known.
Collaborative platform versus industrial cell architecture
One candidate is a collaborative robot platform and the other is an industrial handling platform. Similar payload and reach do not make their safeguarding or teaching workflow equivalent. Assess the delivered safety functions, complete tool geometry, part hazards, required access and productive speed. A collaborative arm can still require guarding for a hazardous tool or task; an industrial arm may require an enclosure or monitored separation. Compare the complete validated installation and recovery procedure, rather than inferring a shared operating mode from the catalogue dimensions.
Selection and acceptance plan
Decision gate | Elephant Robotics Catbot | KUKA LBR iisy 3 R760 |
|---|---|---|
Strongest documented fit | six-axis education and lightweight software experiments within 3 kg and 600 mm | 3 kg collaborative-platform handling within the documented 760 mm working reference |
Main boundary | Desktop education specifications do not establish industrial duty, production precision or a validated collaborative safety package. | Confirm exact configuration, controller, wrist loading and installation envelope. |
Required approval | Exact Elephant Robotics variant, tool load and validated process path | Exact competitor revision, tool load and validated process path |
Acceptance evidence | Agreed parts, path, quality and recovery results | The same agreed parts, path, quality and recovery results |
Advance Elephant Robotics Catbot when six-axis education and lightweight software experiments within 3 kg and 600 mm solves the real constraint and its selected configuration passes the load and access checks. Advance KUKA LBR iisy 3 R760 when 3 kg collaborative-platform handling within the documented 760 mm working reference provides the more suitable process arrangement. Reject either candidate if a mandatory pose, protection requirement or controller function cannot be demonstrated. A purchasing shortlist should preserve these conditions instead of converting a single catalogue advantage into a blanket recommendation.
Before acceptance, agree the representative parts, tool states, operating sequence and quality criteria with both suppliers. Demonstrate cold start, normal production, rejected parts, interrupted cycles and controlled recovery. Record the final tool data and software backup. This turns the comparison into a repeatable purchasing decision and helps prevent a later fixture change from invalidating the original robot selection.
Motion architecture and functionality
Elephant Robotics Catbot has 6 arm axes and KUKA LBR iisy 3 R760 has 6 arm axes. Both have six arm axes; equal axis counts do not establish equal joint travel, inner workspace or fixture access. Compare tool detection, sensing, machine I/O and recovery as separate delivered functions.
Industries and application fit
For Elephant Robotics Catbot vs KUKA LBR iisy 3 R760, use the actual part and process as the industry filter. Electronics, manufactured-component handling and machine tending are candidate uses when their tool mass, access and quality requirements fit the documented configurations. These are application-selection judgments, not claims that either exact model is installed at a named customer. A food, medical-device or clean-production application additionally requires the correct material, lubrication and protection package; the base model name does not establish hygienic or cleanroom compliance.

Frequently asked questions
Which robot is better for this application?
Elephant Robotics Catbot is the stronger starting point for six-axis education and lightweight software experiments within 3 kg and 600 mm, while KUKA LBR iisy 3 R760 is worth shortlisting for 3 kg collaborative-platform handling within the documented 760 mm working reference. The final choice depends on the real loaded path, required protection, controls and acceptance results. Neither a higher payload nor a longer reach establishes a universal winner.
What payload should I use for the comparison?
Use 3 kg for the specified Elephant Robotics Catbot example and 3 kg for KUKA LBR iisy 3 R760, subject to all documented load and orientation conditions. Include the tool, adapters, sensors and carried part. Confirm exact configuration, controller, wrist loading and installation envelope.
Does the stated reach guarantee access to my fixture?
No. The comparison gives 600 mm for Elephant Robotics Catbot and 760 mm for KUKA LBR iisy 3 R760 using the stated model references. Joint limits, reach reference points, wrist orientation, tool length and collisions determine whether the actual fixture is accessible. Simulate the full approach and exit path.
Can I use the best specifications from every family variant?
No. Keep each named model and revision intact. A different arm length, controller generation or protection option can change the relevant specification. Do not combine one version’s maximum payload with another version’s maximum reach.
Is repeatability the same as finished-part accuracy?
No. The stated values are ±0.05 mm for Elephant Robotics Catbot scope and ±0.1 mm for the competitor scope. Finished-part results also depend on fixtures, TCP calibration, sensing, thermal conditions and tool compliance. Validate the actual process instead of treating catalogue repeatability as a complete accuracy guarantee.
How should purchase prices be compared?
Use current written quotations for Elephant Robotics Catbot and KUKA LBR iisy 3 R760 with the same arm, controller, software, tooling and commissioning scope. This comparison does not represent an ATC sales offer or stock confirmation. Historical review figures are not a substitute for a configuration-specific purchase quotation.
Can these robots operate safely next to people without guarding?
These specifications do not establish a safe unguarded installation. Assess the complete task, tool, load and machine interface, then implement and validate the required safeguarding and operating procedures. Do not infer collaborative operation from a compact arm, limited payload or education setting.
What should an acceptance test compare?
Use the same parts, actual tool load, fixture locations, path and quality criteria for Elephant Robotics Catbot and KUKA LBR iisy 3 R760. Check production timing, settling, interruptions and recovery. Include the most difficult loaded approach and retreat. Approve the exact delivered configuration and preserve its final settings.
